AI-powered paydays: coupa-rossum turbocharge global AP, eurowag slashes invoice times

Since forming their strategic partnership in 2024, Coupa and Rossum have deeply integrated Rossum’s AI-powered intelligent document processing into Coupa’s spend management platform, revolutionizing accounts payable automation. This alliance, soon to be cemented by Coupa’s acquisition of Rossum, leverages Rossum’s specialized Transactional Large Language Model (T-LLM) to enable autonomous spend management driven by agentic AI, promising faster invoice processing, significant cost savings, and enhanced control over complex invoicing data.

Rossum’s AI-first architecture marks a decisive departure from legacy optical character recognition technologies by employing a proprietary model trained on tens of millions of documents, which continuously learns and adapts to unique transactional data. This cutting-edge approach delivers rapid time-to-value in accounts payable processing and transactional intelligence that dynamically evolves, positioning Coupa and Rossum’s combined solution as a transformative force in modern finance operations.

Coupa’s CEO Leagh Turner underscores the groundbreaking impact of this integration, highlighting proven successes in automating complex accounts payable invoicing and envisioning expansive AI-driven efficiencies across the entire source-to-pay function. Turner boldly projects that while Coupa has already delivered over US$300 billion in customer savings over two decades, the partnership with Rossum could help realize the next US$300 billion in just five years through an unrivaled system of decision-making and intelligence.

By mid-2026, Eurowag had revolutionized its accounts payable operations by implementing the unified Coupa-Rossum platform, achieving a remarkable 70% automation rate that cut invoice processing time from nine to four days and boosted on-time payments from 60% to over 90%. This transformation replaced fragmented, manual workflows across 60 global entities with a standardized, automated procure-to-pay process, delivering real-time spend visibility and enhanced financial controls. Marcella Mathes, Head of Finance Processes and Digital Finance, emphasized that Coupa's clear, traceable links between purchase orders, receipts, and invoices provide a reliable audit trail that strengthens compliance and fraud prevention.

The success of Eurowag’s finance modernization hinged on a strategic collaboration with Accenture, which designed a scalable core model to unify and automate AP workflows across complex multinational operations. This partnership addressed the challenges of disconnected processes and manual overhead caused by corporate acquisitions, enabling a shift from reactive, siloed tasks to proactive, real-time spend management. As Sam Overton, Rossum’s Regional Vice President, noted, this AI-driven automation transformed accounts payable from a cost center into a value-driven function that delivers strategic insights and reduces operational risk.

Beyond efficiency gains, Eurowag’s AP team experienced a cultural and operational uplift, transitioning from tedious manual data entry to focusing on higher-value activities like supplier relationship management and payment term negotiations. Accounts Payable Manager Petr Podávka highlighted that the team is now both happier and more effective, underscoring how automation not only streamlines processes but also enhances employee satisfaction. This human-centric benefit complements the technological advances, illustrating a holistic finance transformation.

Eurowag’s journey continues with a forward-looking roadmap aiming to push automation rates to 75% by adopting direct API integrations with Coupa, moving away from traditional file transfers. This next-generation AI strategy reflects a commitment to total centralization of global supplier contracts and ongoing innovation in finance operations. The project’s early completion ahead of schedule, praised by Product Owner Vojtěch Podaný, further demonstrates the strong partnership and execution excellence behind this transformative initiative.

The strategic collaboration between Coupa, Rossum, and Accenture has been pivotal in scaling AI-driven accounts payable automation across complex enterprises, exemplified by their joint success with Eurowag. By integrating Rossum’s advanced Transactional Large Language Model and Coupa’s autonomous spend management platform, supported by Accenture’s Reinvention Services—which generated approximately US$70 billion in FY25 revenue and serves 9,000 clients globally—the partnership effectively standardized fragmented procure-to-pay processes and replaced siloed manual workflows with intelligent automation. As Sam Overton, Rossum’s Regional VP, emphasized, this AI foundation transforms accounts payable from a cost center into a value-driven function, showcasing the power of combining human expertise with cutting-edge AI technology.

Coupa’s market leadership in AI-enabled accounts payable solutions is firmly validated by its consecutive recognition as a Leader in Gartner’s 2026 Magic Quadrant for Accounts Payable Applications, highlighting both its execution capabilities and visionary completeness. This acclaim is bolstered by Coupa’s strategic acquisition of Rossum, which, although not included in the Gartner evaluation, significantly enhances invoice processing and document intelligence through AI-driven automation. CEO Leagh Turner underscores this momentum by noting Coupa’s historic delivery of over US$300 billion in customer savings over two decades and the ambition to double that impact in just five years with Rossum’s unrivaled system of decision and intelligence, reflecting strong market confidence and a robust ecosystem connecting over 10 million buyers and suppliers with US$10 trillion in transactional value.
